Abstract
A rooted-forest is a graph having self-loops such that each connected component contains exactly one loop, which is regarded as a root, and there exists no cycle consisting of non-loop edges. In this paper, we shall study on a partition of a graph into edge-disjoint rooted-forests such that each vertex is spanned by exactly d components of the partition, where d is a positive integer.
